The present document specifies that set of technical requirements for Digital Enhanced Cordless Telecommunications
(DECT) Fixed Part (FP) and DECT Portable Part (PP) necessary for the support of the Cordless Terminal Mobility
(CTM) Access Profile (CAP).
The objective of the present document is to ensure the air interface interoperability of DECT CAP PPs and DECT CAP
FPs if applied.
The CTM service allows users of cordless terminals to be mobile within and between networks. Where radio coverage
is provided and the cordless terminal has appropriate access rights the user shall be able to make calls from, and to
receive calls at, any location within the fixed public and/or private networks, and may move without interruption of a
call in progress.
The present document covers the DECT access requirements for CTM phase 2 as defined in the CTM phase 2 service
description, EN 301 273 [14].
The main objectives of the CAP are:
- maintain compatibility with the DECT Generic Access Profile (GAP), identifying only components not
mandatory in the GAP to be added to obtain capabilities needed in the CTM context;
- maintain compatibility with EN 300 175 parts 1 to 8 [1] to [8], for procedures not defined in the GAP.
The CTM access profile is seen as an extension of the GAP mandatory base covering the requirements for CTM
phase 2.
CAP supports telephony teleservice and provides 32 kbit/s Adaptive Differential Pulse Code Modulation (ADPCM)
speech bearer service.
CTM supplementary services with no impact on the air interface are not considered in the CAP.
